The diamond CA-23RP coaxial lightning arrester type BNC interface antenna signal lightning arrester
Brief introduction
The BNC interface lightning protector is a design of
lightning protection applied to the antenna feeder system based on
the relevant standards. It is suitable for all kinds of radio
frequency transceiver systems, wireless network signal
transmitting, satellite TV receiving equipment and monitoring
signal wireless transmitting and receiving equipment. It has high
effective defense function for lightning impulse pulse induced on
the feeder line, and can prevent the antenna and receiving and
receiving equipment caused by the feeder line induced lightning
overvoltage. Damage.

Working principle of product
The lightning protection device is based on the
principle of standing wave antenna and lightning wave spectrum
design. The main part is a short rod equivalent to the end of the
1/4 wavelength. When the signal is sent out, a part of the
impedance is reflected back because the impedance is not fully
matched, and the wave will form a standing wave when the wave is
superimposed on the incident wave originally emitted. The amplitude
of standing wave at each point of the line is fixed first. For the
transmission line with terminal short circuit, the terminal is
short circuited, so the current is large and the voltage is small.
For the signal end, the voltage and the current are small.
That is, the most close to the open circuit of the
signal terminal impedance, so the loss is small, but for the
lightning wave because of its wide spectrum range, and most of the
energy is concentrated in the frequency band below 10HZ, so the
short circuit rod is short circuited to the lightning, and will not
invade the equipment to cause damage.
Use of attention
1. the joints of most antennas are N type, so the two connectors of the surge arrester are two N heads. One is the N public (the antenna), and the other is N mother.
2. in order to reliably prevent thunder and lightning,
we can connect each antenna output terminal and the input terminal
of the protected device to a lightning feeder. In areas where
lightning is less, only one antenna can be used without amplifier.
3. lightning arrester should be connected to the feeder line and installed near the protected equipment.
Product features
1. exquisite workmanship, able to work in bad environment
for a long time.
2. extremely low stationed Bobbi, ensure that the lightning
arrester does not interfere with the normal operation of the
system.
3. low capacitance, inductance design, superior transmission
performance
